CocoaPodsとは
iOS/Mac向けのアプリを作成する際にライブラリ管理をしてくれるツールです。
これを使わない場合、自分でGitHubからライブラリ取ってきて、プロジェクトに手動で追加して…という作業を行なわないといけないため、自動管理してくれるツールとして、非常に便利です。
導入方法
インストール
ターミナルで下記を実行して、インストールします。
$ sudo gem install cocoapods

32 gems installed
CocoaPodsはRubyで書かれているので、gemというパッケージ管理ツールでインストールできます。
gemを使うためにはRubyが入っている必要がありますが、Macでは標準でRubyがインストールされているので、コマンドを実行するだけでインストールできます。
セットアップ
下記コマンドで、利用可能なライブラリ情報の更新を行ないます。
$ pod setup
Setup completed
podfileの作成
プロジェクトファイル(.xcodeproj)と同じディレクトリで、Podfileという名前のファイルを作成します。
サポートするOSのバージョンと、インストールするライブラリを指定します。
今回は、
https://github.com/TimOliver/TOCropViewController
こちらを使いたいので、TOCropViewController を指定します。
platform :ios, "8.0"
pod "TOCropViewController"
platformが何も書かない場合は、iOSの場合6.0以降として設定されます。
ライブラリをインストールする
作成したPodfileがあるディレクトリに移動し、下記のコマンドを実行します。
$ pod install
CocoaPodsで pod install 実行時に起きたエラーの解決方法
下記のようなエラーが出力されるケースがあります。
[!] Could not automatically select an Xcode workspace. Specify one in your Podfile like so:
workspace "path/to/Workspace.xcworkspace"
インストール実行時に、ワークスペースが認識できていないようなので、明示的に記載してあげることで解消します。
workspace "path/to/xxxxxxxx.xcworkspace"
platform :ios, "8.0"
pod "TOCropViewController"
